2 Who Am I? Engineer in Google Open Source Programs Office What do we do? License Compliance Code Release The Summer of Code Protocol, specification and API Licensing Specific Open Source Projects (Samba, git) Also: Co-creator of Samba. Board of Directors of the Software Freedom Conservancy Represent Google on the Gnome Foundation Board Represent Google to the Document Foundation (LibreOffice) Interviewer of Free Software personalities for Google Open Source Blog (etc.) 2

3 A Bit About Open Source Google Confidential 3

4 License Use Across 31m Crawled Files FLOSS License De Duped Files Percentage 14,851, % LGPL 7,145, % BSD 4,245, % Apache 1,778, % MIT 1,565, % Mozilla 567, % Perl 333, % QPL 206, % Artistic 150, % CPL 144, % GPL 4

5 Why do people release code at all? A BCG/OSDN Study found that open source developers are motivated by: Intellectual Curiosity/Stimulation (44.9%) Skills Improvement (41.3%) Work needs (33.8 %) Open Source Idealism (33.1%) Non-Work Functionality (29.7%) Professional Status (17.5%) Reputation building within Open Source (11%) Dislike/distrust of proprietary software (11.1%) 5

6 Implications: FLOSS developers understand OSS licenses. They know they are giving away their software. They know and hope people will use it. The majority expect no more $$$ for the work. If they did, they d just do it as a commercial offering, if they can. Which is pretty remarkable. 6

7 The Result: Enterprise-level software is being created and released by professionals for free, under licenses which encourage commercialization and reuse If you're building a business that uses software without basing it on Open Source/Free Software you are throwing money away Almost every new product containing an embedded computer is being built with Open Source/Free Software Phones, TV's, Cars, DVRs, Networks too many to list Which is even more remarkable 7

15 What is Google In-house rack design PC-class motherboards Low-end hardware, mostly Running Linux + in-house software 15

16 How does Google use Open Source? As Infrastructure Linux kernel Many Apache Project Tools SSH, and other system management tools The Languages and compilers that we use (gcc, llvm, Java, Go, Python). Engineers and others running Linux (Goobuntu) As building blocks Our repositories have thousands of libraries used in Google software (Mostly) automated process tracks license use 16

17 Why does Google use Open Source? 17

18 I'm sorry Google, I can't let you do that.. 18

19 But Why does Google use Open Source (and why you should too) Control and Ownership Maintain our independence from external software companies Adaptability and Flexibility We can drill down to repair and enhance our services If we want to do something out of the ordinary, we can do so without showing our hand No one is incentivized to hurt us Roots Appeals to the Google ethic (It's really all the reasons to use Free Software but people are scared of the 'F' word..) 19

20 But we're not Google! You don't have to be Google to take advantage of Open Source/Free Software In times of austerity, use resources to build up LOCAL talents and businesses Programmers live everywhere no country has a monopoly on smart people Invest in your own PEOPLE, not in becoming mere users of someone else's software Fund local improvements, take control of your own IT Create local communities around the software you use Ensure a pool of talent you can draw on for improvements, documentation 20 Encourage commercialization of Free Software/Open Source

21 How does Google take part? 21

22 Google s Open Source Programs Patching and Code Release Internal License Discipline API/Protocol License Discipline Open Source Infrastructure & Leadership Summer of Code Donations/Funding/Sponsorship Industry Trade Group Participation 22

23 Open Source Infrastructure Hosting on Google Code which provides: Reliable, scalable, clean project Hosting Version Control (git,hg, svn) Issue/Bug Tracking Wikis Over 600k projects of projects, now the 2nd Largest Repository Online 23

24 We release open source code We Patch into hundreds of projects each month Strategically important Helps the Internet grow fairly. >3400 small projects to date. API Examples Dev Tools Linker Build/test Memory and thread management Plug-ins for eclipse DVCS patches (git and jgit). Infrastructure Approximately 30m lines of code released Some across many large projects.. Samba for example

25 Large Project Releases? 25

26 Major Projects: Chromium/ChromiumOS What is it: A browser What license: Mostly BSD (some LGPL) What does it do? Incredibly Fast Safe, smart, sandboxing Multiple processes/tab. Implements HTML5 Offline, Worker pools, Geo-location, File uploading Desktop like experiences inside the browser ChromiumOS Reducing Linux to a poorly debugged set of device drivers :-)

27 Major Projects: Android What is it: Full cell phone OS. What license: Apache + Linux Kernel What does it do? Raises the minimum bar for smart phone OS Allows for a solid web experience Allow for multiple applications to co-exist. Provides a smart app marketplace Makes cell phone development a snap Base platform to create a tablet market 1,000,000+ devices activated daily

28 WebM What it is: WebM is an open, royalty-free, media file format designed for the web. Vorbis Audio Vp8 video In a matroska-like (MKV) container Very high quality Releasing in a very open source way. BSD licensed Patents granted freely, no fees required. Our goal is to get html5 to recognize webm as a standard codec for web video/audio.

29 Other significant open source technology releases WebP WebRTC Omaha Ganeti Android ADK robot code (and ADK!) White spaces Geographical database M-Lab (600Tb of network speed surveys)

30 Summer of Code 30

31 The Summer Of Code, students 170 Organizations Over 2000 Mentors >6000 applications 87 Countries 86% pass rate! ~3 million lines of code in 2011 alone (~21m since 2005) 31

32 How it Works 1) Student applies to work on a project for, say, the ASF 2) ASF mentors review the application and accept the student 3) Google pays student $500 for being accepted 4) Student works with an ASF mentor to create project 5) Mid-Term, good students are paid $2250 by Google 6) Student continues work with mentor to create project 7) Final: If the student has completed the goals set forth in the application and student is paid $2250 by Google 8) Successful student gets t-shirt, certificate and valuable experience along with the money. 32

33 Sponsorship 33

34 Google OSPO sponsors many FLOSS organizations both commercial and non-profit Linux Foundation Gnome Foundation Document Foundation Free Software Foundation Software Freedom Conservancy Apache Foundation Samba Team (and many more) 34

35 Google and Standards 35

36 Google and Standards Google strongly supports Internet Standards Vint Cerf (one of the Fathers of the Internet ) is the head of Google's Standards Group Ian Hickson (author and maintainer of HTML5 specification) works for Google OSPO Google is built on Internet Standards Open Source/Free Software needs open standards to interoperate with proprietary systems 36

37 Google and Standards Data Liberation Front Can I get my data out in an open, interoperable, portable format? How much is it going to cost to get my data out? How much of my time is it going to take to get my data out?

38 The End Questions? 38
